We’ve Updated Our Case Series.
Names like Ultra-Slim, ProGuard, and UltraGuard helped describe features, but over time, they also caused confusion.
At PITAKA, we’ve always focused on advancing aramid fiber weaving to improve everyday carry. As our products evolved, we wanted our names to reflect the experience, not just the specs. That’s why we renamed our three series asCairn, Edge, and Summa— inspired by a journey of climbing:* Edge: slim, light, and sharp along the climb (Original name: Ultra-Slim Case)
* Cairn: firm and dependable, like stone markers that guide the way (Original name: ProGuard Case)
* Summa: the peak, where protection and hand-feel come together (Original name: UltraGuard Case)

Yes! This is the Christmas Limited Edition Gift Set, which includes:

• 1 × Threads of Winter Phone Case
• 1 × Pair of Christmas Socks
• 1 × Product Card
• 1 × User Manual
• 2 × Protective Pads
  
  

Yes. The case is crafted using high-strength aramid fiber weaving technology — every pattern and texture is woven, not printed.

Absolutely. Each case is laser-engraved with its own unique serial number, part of a worldwide limited edition of 6,000 sets.

The socks measure 26–28 cm in length and are made from 70% cotton, 26% polyester, and 4% spandex. They offer excellent stretch, fitting most foot sizes, or simply serve as a cozy decorative touch.

The Edge series is designed to be extremely thin and light, providing a bare-metal-like experience.       It offers sufficient protection against daily scratches and minor impacts. However, for stronger shocks or drops, the protection level may not match that of the Cairn or Summa series. If protection is your priority, we recommend choosing one of those alternatives.

 Yes, all Threads of Winter series cases support lens protectors. However, due to the closer-fitting camera ring design of the Cairn model, some lens protectors may have slight fit issues.

Yes, the Threads of Winter case does not interfere with the use of a tempered glass screen protector. Its edges are designed to sit nearly flush with the screen, providing a comfortable grip while helping preserve the original feel and look of the iPhone as much as possible. Please note that with this design, a tempered glass protector may sit slightly higher than the case edges, but this will not affect normal use.

Yes. All iPhone 17 series cases have a built-in magnetic ring, supporting MagSafe and PITAKA accessories,including MagEZ Car Mount Pro, MagEZ Grip, Aramid Magnetic Power Bank, and Magnetic Woven Wallet.

To provide a skin-friendly feel, the case surface is coated. Fingerprints may occasionally appear due to hand sweat or lotion, but they can be easily wiped away with a wet wipe, alcohol pad, or even an eraser. Use with confidence.

No. Our cases are carefully designed and tested to be compatible with mainstream wireless chargers. You can charge your phone without removing the case.
